摘要

Animals interact with mates in a sensory environment rife with the footprints of human activities.Frogs chorus over the noise of traffic(Bee and Swanson 2007),glow-worms search for bioluminescent mates against backlight from street lamps(Bird and Parker 2014),and fish attend to conspecific olfactory cues mixed with sewage(Fisher et al.2006).As invasive species proliferate throughout the world,animals also encounter noise in the form of novel heterospe-cific signals that can interfere with existing communication channels(Gr?ning and Hochkirch 2008).Pheromones,for example,are often species-specific in natural contexts involving sympatric heterospe-cifics but may become detrimental pollution when animals invade regions inhabited by historically allopatric relatives that previously faced less selection for signal divergence(Gozlan et al.2014).Sea lamprey Petromyzon marinus are a destructive invader of the Laurentian Great Lakes whose pheromones may disrupt communi-cation in native species.The Laurentian Great Lakes host four na-tive species of lamprey who spawn at overlapping times and places as P.marinus,with peak spawning for three native lampreys and P.marinus occurring simultaneously(early Tune;Johnson et al.2015).
